SPECIFICATION forming part of Letters Patent No. 465,123, dated December15, 1891.

'Application filed April 24, 1891.

T0 to whom, it may concern.-

Be it known that I, J AMES ROBINSON BALS- LEY, of Connellsville, in thecounty of Fayette and State of Pennsylvania, have invented a new andImproved Shipper, of which the following is a full, clear, and exactdescription.

My invention relates to an improvement in a shipper; and the object ofmy invention is to produce a convenient shipper, by means of which thebelt may be shifted from the tight to the loose pulley, or vice versa,and to construct the shipper in such a manner that it will start thebelt in the right direction when it is shifted from the loose to thetight pulley.

To this end my invention consists in certain features of constructionand combinations of parts, which will be hereinafter described andclaimed.

' Reference is to behad to the accompanying drawings, forming a part ofthis specification, in which similar figures of referenceindieatecorresponding parts in all the views.

Figure 1 is a broken side elevation of the improvement applied, the beltbeing shown in section. Fig. 2 is a sectional plan on the line 2 2 inFig. 1, showing the shipper in position to hold the belt upon the tightpulley. Fig. 3 is a similar view, but with the shipper in position tohold the belt upon the loose pulley. Fig. 4 is a cross-section on theline 5 5 in Fig. 1, showing the belt-clutch in detail. Fig. 5 is abroken side elevation showing the general arrangement of thedrivingshaft, hanger, shipper, and driving-belt.

The driving-shaft 10 may be supported in any suitable hangers, and it isprovided with a tight and loose pulley 11 and 12, the pulley 11 beingsecured to the shaft in the ordinary way; but the pulley 12 ispreferably mounted independently of the shaft and on a hanger 14.,provided with an arm 15, which is adapted to be secured to a support.

The shipper is arranged adjacent to the driving-shaft and to the pulleys11 and 12,

. and consists of the following mechanism: An

arm 21 is pivoted on a hanger 21, and is arranged so as to extendhorizontally on a line with the upper portion of the driving-belt 13,and this arm is provided near one end with a depending shoulder 22 andat the extreme end it is bent downward opposite the shoul- Serial No.390,268. (No model.)

der, as shown at 23, and the bolt 13 is arranged to run between the bentend and the shoulder. The shoulder 22 is recessed near its upperportion, and pivoted in the recess is a spool-pulley 24, which isadapted to contact with the belt 13 when the belt is shifted upon thetight pulley, and the spool will thus serve to prevent excessivefriction. A dog 25 is pivoted on the shoulder 22, the shank of the dogextending downward and the upper end of it being rounded slightly andadapted to contact with the belt 13. The length of the dog is suchbetween its pivoted end and the arm 21 that when the dog is thrown intoa vertical position, as best shown in Fig. 5, its upper end will impingeupon the belt and clamp it tightly between the dog and the arm 21. Thelower end of the dog is connected by a link 26 to a link 26, pivoted toa bent lever 27, which extends downward and outward and is pivoted tothe lower end of the hanger 21. The outer end of the lever 27 isconnected by a pull-rod 28 with a lever 29, which is pivoted at itsupper end to the ceiling, and which extends downward to a point where itmay be conveniently reached by the hand.

I have shown the lever 29 adjacent to a counter-shaft 30, and the levermay be made to extend to a point adjacent to a machine, so that theoperator of the machine may conveniently grasp the lever. I do notconfine myself, however, to any particularlever mechanism for operatingthe lever 27.

The operation of the shipper is as follows: If the belt 13 is on theloose pulley, as shown in Fig. 3, the shipper will be in the positionindicated in the same figure, and to shift the belt from the loose tothe tight pulley the rod 28 is pulled forward by means of the lever 29and the outer end of the lever 27 will be drawn forward. This will swingthe dog 25 so that it will clamp the belt 13 between it and the arm 21,and the lever and arm will both swing forward, as indicated by the arrowand broken lines in Fig. 3. The pulley 2 1 will crowd the belt over uponthe tight pulley, and the movement of the arm 21 and lever 27 will startthe belt forward, so that it will not be given so sudden a snap when itstrikes the tight pulley, as would be the case if it were pusheddirectly upon the pulley. hen the tight pulley, the movement of the beltreleases the dog, and the shipper is ready for the reverse movement.When the belt is to be thrown from the tight pulley to the loose, theabove operation is reversed, and the bent end 23 of the arm 21 does theshipping.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A shipper comprising a hanger, an arm pivotedthereon, said arm terminating at one end in a depending bend and havinga shoulder opposite the bend, a dog pivoted on the shoulder and adaptedto impinge against the arm, a lever pivoted to the lower end of the dogand to the hanger, and means for operating the lever, substantially asdescribed.

2. The combination of a swinging arm having a bent end and a shoulderopposite said end, a clamping device for the belt arranged upon theshoulder, and a pulley pivoted on the shoulder and adapted to contactwith the belt, substantially as described.

3. A shipper comprising a hanger, an arm pivoted thereon and providedwith abent end, a shoulder opposite said bent end, a pulley pivoted inthe shoulder and adapted to contact with the belt, a dog pivoted on theshoulder and adapted to swing at right angles to the arm, a leverpivoted to the lower end of the dog and to the hanger, and mechanism foroperating the lever, substantially as described.
